KMG CHEMICALS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

The consolidated balance sheet as of July 31, 2011, which has been derived from audited consolidated financial
statements, and the unaudited condensed consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting. As permitted under those
requirements, certain footnotes or other financial information that are normally required by generally accepted accounting principles in the United States of America (GAAP) have been condensed or omitted. The Company believes that the
disclosures made are adequate to make the information not misleading and in the opinion of management reflect all adjustments, including those of a normal recurring nature, that are necessary for a fair presentation of financial position and results
of operations for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of results of operations to be expected for the full year. The unaudited condensed consolidated financial statements
included herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Companys Annual Report on Form 10-K for the year ended July 31, 2011.

These condensed consolidated financial statements are prepared using certain estimates by management and include the accounts of KMG
Chemicals, Inc. and its subsidiaries (collectively, the Company). All significant intercompany balances and transactions have been eliminated in consolidation.

Certain reclassifications have been made to the prior period consolidated financial statements to conform to the current period presentation.

The consolidated balance sheet as of July 31, 2011 reflected a reclassification of certain accrued taxes payable to Accounts
receivable  other to conform to the current period presentation. The current period presentation included a net receivable reflecting the offset of the respective tax receivable and tax payable associated with the same tax jurisdiction.
This reclassification had no impact on the historical consolidated statements of income or retained earnings.

During the
third quarter of fiscal year 2012 the Company sold its animal health business and reported the related results of operations as discontinued operations in its condensed consolidated statements of income. Previously reported amounts for each of the
prior year periods presented have been adjusted for the effects of discontinued operations (see Note 2).

The Company began
classifying certain expenses as selling, general and administrative expenses in the fourth quarter of fiscal year 2011 which had previously been reported as distribution expenses. Accordingly, the three and nine months ended April 30, 2011,
were reclassified to conform to the current year presentation.

2. Discontinued Operations

In fiscal year 2008 the Company discontinued operations of its herbicide product line that had comprised the
agricultural chemical segment. During fiscal year 2011 the Company began dismantling the related equipment at its Matamoros, Mexico facility. In connection with the dismantling of the equipment an accident occurred during the second fiscal quarter
of 2012 resulting in the injury of two third-party contractors. The Company incurred costs in each of the periods reported for equipment dismantlement, and in addition, the current year periods included medical and other expenses associated with the
accident. The Company reported the costs in loss from discontinued operations, before income taxes, which included $200,000 and $57,000 for the three months ended April 30, 2012 and 2011, respectively, and $580,000 and $104,000 for the
nine months ended April 30, 2012 and 2011, respectively, reported as loss from discontinued operations, before income taxes.

On March 1, 2012, the Company sold its animal health business that had comprised the animal health segment to Bayer Healthcare LLC.
The sale included inventory, equipment and product registrations. The Company retained the real estate and buildings at its facility in Elwood, Kansas. The Company sold the business for approximately $10.2 million, including $1.0 million in
restricted cash held in escrow. The purchase price was paid in cash, subject to the escrow. The escrowed amount is to be held pending final acceptance by the United States Environmental Protection Agency (EPA) of certain studies being
performed at the request of the EPA on tetrachlorvinphos, the active ingredient used in Rabon products. The escrowed funds are to be released to the Company once the EPA has finally accepted the studies, the buyer has voluntarily canceled the
products, or after five years. The escrowed funds are to be released to the buyer if the EPA cancels the products to which the studies pertain before the funds are distributed to the Company. Management believes that the EPA will accept the studies
within five years.

The Company will continue to operate the facility in Elwood, Kansas to manufacture products for the buyer
under a transition services agreement for one year, subject to two six-month extensions. The Company evaluated the transition services agreement and concluded that it did not represent significant continuing involvement or a continuation of
activities by the Company in accordance with GAAP.

Series 1: Vesting for the Series 1 awards is subject to a performance requirement composed of certain
revenue growth objectives and average annual return on invested capital or equity objectives measured across a three year period. These objectives are measured quarterly using the Companys budget, actual results and long-term projections. For
the fiscal year 2012, 2011 and 2010 awards, the expected percentage of vesting is based on performance through April 30, 2012 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement
periods.

Series 2: Vesting for the Series 2 awards is subject to performance requirements pertaining to the growth rate in
the Companys basic earnings per share over a three year period. The achievement of performance requirements is measured quarterly using the Companys budget, actual results and long-term projections. For the fiscal year 2012, 2011 and
2010 awards, the expected percentage of vesting is based on performance through April 30, 2012 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement periods.

The weighted-average grant-date fair value of performance awards outstanding at April 30, 2012 and August 1, 2011 was $14.98
and $15.60, respectively. The weighted-average grant date fair value of performance awards granted during the first nine months of fiscal year 2012 was $14.41.

During the nine month period ended April 30, 2012 there were 19,624 shares vested. The number of shares presented here includes an adjustment of
851 shares which do not represent shares that vested during the nine months ended April 31, 2012. The adjustment was related to the fiscal year 2011 non-employee director stock grant and reflects the difference between the number of shares
reported as granted and the number of shares vested over the twelve month service period of the award ended November 30, 2011. The number of shares granted was calculated based on the aggregate monetary value of the award divided by the
Companys closing stock price on the respective date of grant. The number of shares vested at the end of each of the three month service periods over the twelve month service period ending November 30, 2011 was based on the Companys
closing stock price at the end of each of the three month periods.

quarter of fiscal year 2012 the Company re-evaluated the criteria used to determine operating segments and concluded that Penta and Creosote met the criteria of a single operating segment. As a result, during the first quarter of fiscal year 2012,
the composition of the Companys reportable segments was revised to reflect a change combining those two reportable segments. The Company sold its animal health business on March 1, 2012, and that former segment is now reported as
discontinued operations. Prior year information has been reclassified to conform to the current period presentation.

Other corporate expense primarily represents employee stock-based compensation expenses and those expenses associated with the companys operation
as a public entity such as board compensation, audit expense and fees related to the listing of our stock. The amounts presented include corporate overhead previously allocated to the animal health business. These amounts were not reallocated to the
remaining segments.

To finance the acquisition of the electronic chemicals business in December 2007, the Company entered
into a credit agreement and a note purchase agreement with Wachovia Bank, National Association, a subsidiary of Wells Fargo & Co., Bank of America, N.A., The Prudential Insurance Company of America, and Pruco Life Insurance Company. The
credit agreement included a term loan facility and a revolving loan facility. The Company amended the credit agreement in March 2010 and November 2011. The November 2011 amendment of the credit facility raised the maximum amount that may be
borrowed under the revolving loan facility from $50.0 million to $60.0 million, extended the maturity date of the credit agreement to December 31, 2016 and allowed advances under the revolving loan facility without reference to a borrowing
base restriction. The financial covenant for debt to capitalization was replaced by a current ratio minimum of 1.5 to 1.0. The Company had previously paid off all outstanding advances under the credit facilitys term loan commitment, and in the
November 2011 amendment, that aspect of the facility was deleted. The revolving loan bears interest at a varying rate of LIBOR plus a margin based on our funded debt to earnings before interest, taxes, depreciation and amortization
(EBITDA).

Advances outstanding under the revolving loan facility bear interest of 2.24% as of April 30, 2012
and June 1, 2012 (LIBOR plus 2.00%).

Before the term loan facility was paid off and removed from the credit facility,
the term facility required principal payments of $458,333 per month for the first 24 months, then, beginning January 2010, principal payments became $666,667 per month for the balance of the term prior to maturity. The purchase of the electronic
chemical assets from General Chemical on March 29, 2010 was funded with available cash and borrowings on the revolving loan. During the first quarter of fiscal year 2012 the Company repaid the outstanding balance of the term loan with
borrowings on the revolving loan. The Company used the proceeds received on the sale of its Animal Health business to repay $10.0 million of the balance on the revolving loan facility on March 2, 2012. The amount outstanding on the revolving
loan facility at April 30, 2012 was $8.0 million.

At July 31, 2011 the Company had a book overdraft of
$2.9 million, which represented the amount in excess of the bank balance that was necessary to fund checks that were paid but not yet cleared. GAAP requires that the book overdraft be classified as a current liability on the consolidated
balance sheets. For purposes of reporting cash flows, the Company reports the book overdraft as a financing activity. There was no book overdraft as of April 30, 2012.

In fiscal year 2008 the Company also entered into a $20.0 million note purchase agreement with the Prudential Insurance Company of America. Advances under the note purchase agreement mature
December 31, 2014, and bear interest at 7.43% per annum. Principal is payable at maturity. At April 30, 2012, $20.0 million was outstanding under the note purchase agreement.

Loans under the amended and restated credit facility and the note purchase agreement are secured by the Companys assets, including
inventory, accounts receivable, equipment, intangible assets, and real property. The credit facility and the note purchase agreement have restrictive covenants, including that the Company must maintain a fixed charge coverage ratio of 1.5 to 1.0, a
ratio of funded debt to EBITDA of 3.0 to 1.0, and a current ratio of at least 1.5 to 1.0. For purposes of calculating these financial covenant ratios, we use a pro forma EBITDA. On April 30, 2012, the Company was in compliance with all of its
debt covenants.

11. Income Taxes

Income tax expense for the interim periods was computed using the effective tax rate estimated to be applicable for
the full fiscal year. The effective tax rate for continuing operations for the third quarter of fiscal years 2012 and 2011 was 38.3% and 34.4%, respectively and 39.2% and 33.8% for the nine months ended April 30 of fiscal years 2012 and 2011,
respectively. Income tax expense for the prior year periods was reduced by $208,000 and $618,000 during the three and nine months ended April 30, 2011, respectively for the reversal of the valuation allowance related to a foreign subsidiary.

Earnings associated with our foreign subsidiaries are considered to be permanently reinvested, and no provision for United
States federal and state income taxes on these earnings or translation has been provided.

12. Litigation and Other Contingencies

The Company is subject to contingencies, including litigation relating to environmental laws and regulations,
commercial disputes and other matters. Certain of these contingencies are discussed below. The ultimate resolution of these contingencies is subject to significant uncertainty, and should the Company fail to prevail in any of them or should several
of them be resolved against the Company in the same reporting period, these matters could, individually or in the aggregate, be material to the consolidated financial statements. The ultimate outcome of these matters cannot be determined at this
time, nor can the amount of any potential loss be reasonably estimated, and as a result no amounts have been recorded in the Companys condensed consolidated financial statements except where noted.

15

A lawsuit was filed against our wholly-owned subsidiary, KMG de Mexico, relating to the
title to the land on which our facility in Matamoros is located. The plaintiffs claim that their title to the land is superior to the person from whom our subsidiary bought the land. The plaintiffs are seeking to have our subsidiarys purchase
overturned, and to recover the land and certain improvements or their value. The lawsuit was initially filed in 1998 in Matamoros, Mexico under Adolfo Cazares Rosas, et al vs. KMG de Mexico and Guillermo Villarreal. In January 2008, the case
was sent by the appeals court back to the lower court to obtain additional factual information, and on April 20, 2009 the plaintiffs were required to re-file the case in the First Civil Court in Matamoros, Tamaulipas, Mexico as Adolfo
Cazares, Luis Escudero and Juan Cue vs. KMG de Mexico and Guillermo Villarreal. In June 2011 the lower court ruled against KMG de Mexico, and held that the plaintiffs had superior title to the land, but that verdict was overturned on appeal in
May 2012, and the case has been returned to the trial court for further action. The Company intends to continue to vigorously defend KMG de Mexico.

When it purchased assets from Air Products, Inc. (Air Products) in December 2007, the Company agreed to be responsible for the applicable sales tax on the personal property that it purchased.
The Colorado Department of Revenue audited the purchase, and in November 2009 issued a deficiency notice to Air Products for unpaid sales tax on the purchase of approximately $819,000, before interest and penalties. The Company assumed the defense
of the matter as allowed under its indemnity of Air Products. The Company classified certain property at the Companys Pueblo facility as real property not subject to tax, not as personal property subject to sales tax. The matter is now being
reviewed internally at the Colorado Department of Revenue. If a satisfactory resolution is not reached, the dispute would be subject to arbitration. In the second quarter of fiscal year 2012, the Company recognized approximately $100,000, including
taxes, penalties and interest, related to certain property that it concluded was personal property and subject to sales tax.

The Companys subsidiary in Italy is currently under examination by the taxing authority there for the period ended
July 31, 2009. Adjustments were proposed by the taxing authority at the end of April 2011 that would result in approximately $1.6 million (including interest and penalties) of additional income tax, if all the adjustments are
sustained. The Company has provided additional information in response to the proposed adjustments, and intends to vigorously defend its tax positions. The ultimate outcome of this examination is subject to uncertainty and no amount has been
recorded in the Companys consolidated financial statements.

The Company is subject to federal, state, local and foreign
laws and regulations and potential liabilities relating to the protection of the environment and human health and safety including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the emission of
substances into the air or waterways, and various health and safety matters. The Company expects to incur substantial costs for ongoing compliance with such laws and regulations. The Company may also face governmental or third-party claims, or
otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues for environmental liabilities when a determination can be made that they are
probable and reasonably estimable. No accrual has been recorded as of April 30, 2012.

ITEM 2.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We manufacture, formulate and distribute specialty chemicals globally. We operate businesses engaged in electronic chemicals and
industrial wood treating chemicals. Our electronic chemicals are used in the manufacturing of semiconductors. Our wood treating chemicals, pentachlorophenol (penta) and creosote are used by our industrial customers primarily to extend
the useful life of utility poles and railroad crossties.

Sale of the Animal Health Business

On March 1, 2012, we sold certain assets of our animal health business to Bayer Healthcare, LLC for a purchase price of
approximately $10.2 million, including $1.0 million held in escrow. The purchase price was paid in cash, subject to the escrow, and we used the proceeds to reduce the amount outstanding on our revolving indebtedness. The escrowed amount is
being held pending final acceptance by EPA of certain studies being performed at its request on tetrachlorvinphos, the active ingredient used in Rabon products. The escrowed funds are to be released to us once the EPA has finally accepted the
studies, the buyer has voluntarily canceled the products, or after five years. The escrowed funds are to be released to the buyer if the EPA cancels products to which the studies pertain before the funds are distributed to us. The sale included
inventory, equipment and product registrations. We retained the real estate and building at our facility in Elwood, Kansas, and we will operate it to manufacture products for the buyer under a transition services agreement for one year, subject to
two six-month extensions.

Three and Nine Month Periods Ended April 30, 2012 compared with Three and Nine Month Periods Ended April 30, 2011

Segment Data

Segment data is presented for our two reportable segments
for the three and nine month periods ended April 30, 2012 and 2011. The segment data should be read in conjunction with our condensed consolidated financial statements and related notes thereto included elsewhere in this report. We previously
had four reportable segments for electronic chemicals, penta, creosote and animal health. During the first quarter of fiscal year 2012 we re-evaluated the criteria used to determine operating segments and concluded that our two wood treating product
segments met the criteria of a single operating segment. As a result our reportable segments were revised to reflect a change combining those two reportable segments. The animal health business was sold in March 2012, and results of that former
segment are included as discontinued operations. Prior year information has been reclassified to conform to the current period presentation.

Net Sales

Net sales increased $4.7 million, or 7.6%, to $66.6 million in the third quarter of fiscal year 2012 as compared to $61.9 million for the same period of the prior year. For the nine months,
net sales increased $20.4 million, or 11.1%, to $205.1 million in the first nine months of fiscal year 2012 as compared with $184.7 million for the same period of the prior year.

In the third quarter of fiscal year 2012, the electronic chemicals segment had net sales of $39.4 million, an increase of $913,000, or
2.4%, as compared to $38.5 million for the prior year period. For the nine month period, the segment had net sales of $116.4 million, an increase of $5.1 million, or 4.6%, as compared to $111.3 million in the prior year. We
implemented price increases over the past twelve months in response to increased raw material costs. We expect demand for our electronic chemicals products to improve in calendar 2012, and we will have additional business from a new semiconductor
fabrication facility that has come on stream.

Net sales of wood treating chemicals increased $3.8 million, or 16.1%, to
$27.2 million in the third quarter of fiscal year 2012 as compared to $23.4 million for the prior year period. For the nine month period, the segment had net sales of $88.7 million, an increase of $15.3 million, or 20.9%, as compared to
$73.4 million in the prior year. The increase in net sales for the quarter was due primarily to increases in price, while the increase for the nine month period was attributable almost evenly to higher volumes and increases in price. We expect
to see generally flat demand in the segment through the balance of the fiscal year.

Gross Profit

Gross profit increased by $3.8 million, or 22.9%, to $20.6 million in the third quarter of fiscal year 2012 from $16.8 million in
the same quarter of the prior year. Gross profit as a percentage of sales increased to 30.9% in the third quarter of fiscal year 2012 from 27.1% in the third quarter of fiscal year 2011. For the nine month period, we had gross profit of
$56.4 million, an increase of $5.3 million, or 10.4%, as compared to $51.1 million in the prior year. Gross profit as a percentage of sales was flat for the nine months at 27.5% in fiscal year 2012 and 27.7% in the prior fiscal year.

The increase in aggregate gross profit for the quarter was due primarily to pricing action in the electronic chemicals
segment and, now that our consolidation is complete, lower manufacturing costs.

Other companies may include certain of the
costs that we record in cost of sales as distribution expenses or selling, general and administrative expenses, and may include certain of the costs that we record in distribution expenses or selling, general and administrative expenses as a
component of cost of sales, resulting in a lack of comparability between our gross profit and that reported by other companies.

Distribution Expenses

Distribution expenses were flat at $7.4 million in both the third quarter of fiscal year 2012 and in the prior year period.
Distribution expenses were approximately 11.1% and 12.0% of net sales for the third quarter of fiscal years 2012 and 2011, respectively. For the nine month period, we had distribution expenses of $19.3 million, a decrease of $1.5 million,
or 7.0%, as compared to $20.7 million in the prior year. Distribution expense as a percentage of sales decreased for the nine months to 9.4% in fiscal year 2012 from 11.2% in the prior fiscal year 2011. The decrease in distribution expenses was
attributable to electronic chemicals, which resulted from efficiency improvements in our supply chain and the completion of our integration effort. The decline in distribution expense as a percentage of revenue was attributable fairly evenly to
efficiency improvements in the electronic chemicals business and an increase in the weighting of wood treating chemicals share of total revenue. The electronic chemicals business comprises over 75% of our distribution expenses.

17

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $1.1 million, or 21.3%, to $6.3 million in the third quarter of fiscal
year 2012 from $5.2 million in the same quarter of fiscal year 2011. Those expenses were 9.5% and 8.4% of sales in the third quarter of fiscal years 2012 and 2011, respectively. For the nine month period, we had selling, general and administrative
expenses of $18.4 million, an increase of $2.5 million, or 15.9%, as compared to $15.9 million in the prior year. Those expenses as a percentage of sales were 9.5% in fiscal year 2012 and 8.4% in fiscal year 2011 for the third quarter
comparison, and were 9.0% in fiscal year 2012 and 8.6% in fiscal year 2011 for the nine month comparison. For the three months ended April 30, 2012, the increase over the prior year was due to employee related expenses and for the nine months
ended April 30, 2012, the increase was mainly due to higher employee related costs and non-recurring environmental costs of $1.7 million and $1.1 million, respectively. The environmental expenses were for waste disposal at our Tuscaloosa
facility in connection with waste generated on installation of new dissolving equipment, from disposal of out of specification material and from disposal of creosote waste associated with cleaning rail cars.

Interest Expense

Interest expense was $504,000 and $571,000 in the third quarter of fiscal year 2012 and 2011, respectively, and $1.6 million and
$1.8 million in the first nine months of fiscal year 2012 and 2011, respectively. The decrease was due to lower borrowings on our loan facility in fiscal year 2012 as compared to the same periods of the prior year, in part because we paid off
the outstanding balance of $11.3 million on our term loan under that facility in the first quarter of fiscal year 2012.

Income Taxes

Our effective tax rate for continuing operations was 38.3% and 34.4% in the third quarter of fiscal years 2012 and 2011,
respectively, and 39.2% and 33.8% for the first nine months of fiscal years 2012 and 2011, respectively. The prior year period income tax expense was net of discrete period adjustments reflecting the reversal of the valuation allowance related to a
foreign subsidiary of $208,000 and $618,000 during the three and nine months ended April 30, 2011, respectively.

Discontinued
Operations

Discontinued operations reflected a net gain of $66,000 and $232,000 for the three month periods ended
April 30, 2012 and 2011, respectively, and a net loss of $333,000 and a net gain of $195,000 for the nine month periods ended April 30, 2012 and 2011, respectively. We incurred expense in each of the periods in connection with the
dismantling of the production facility related to the agricultural chemical segment that was discontinued in fiscal year 2008. The current year periods also included expense related to an accident at our Matamoros facility during the dismantlement
of that facility. We recognized a pre-tax gain of approximately $90,000 on the sale of the animal health business. We also recognized a pre-tax gain on the results of operation of that business during the three months ended April 30, 2012
and 2011 of $292,000 and $442,000, respectively, and a pre-tax gain of $56,000and $438,000 for the nine month ended April 30, 2012 and 2011, respectively.

Liquidity and Capital Resources

Cash Flows

Net cash provided by operating activities was $22.9 million for the first nine months of fiscal year 2012 as compared to
$10.0 million for the comparable period in 2011. Net income adjusted for depreciation and amortization increased cash $15.2 million in the first nine months of fiscal year 2012 as compared to $14.3 million over the same period of the
prior year. Cash flows from operating activities during the current period were favorably impacted by a decrease in trade accounts receivable of $7.2 million and an increase in income taxes payable of $2.3 million. The reduction in trade
accounts receivable was due to normal collections activity in our electronic chemicals segment, timing of sales in our wood treating segment and lower balances related to the animal health business which was sold on March 1, 2012. The increase
in income taxes payable was associated with the current year income tax accrual. Operating cash flows were unfavorably impacted by an increase in inventories of $4.6 million resulting mainly from the timing of creosote purchases.

Net cash provided by investing activities in the first nine months of fiscal 2012 was $5.3 million as compared to $5.6 million
of net cash used in the prior year period. In fiscal year 2012, we received proceeds of $10.2 million from the sale of our animal health business. The additions to property, plant and equipment were $3.9 million and $5.8 million in
fiscal years 2012 and 2011, respectively. In fiscal year 2012, the majority of the additions were for electronic chemicals distribution and production equipment. In fiscal year 2011, the additions were primarily for expansion at our Hollister,
California facility and for equipment at Pueblo, Colorado. During the current period cash and cash equivalents were reduced by $1.0 million for cash that was restricted in connection with the escrowed amount on the animal health sale.

Net cash used in financing activities was $24.8 million in the first nine months of fiscal year 2012 as compared to
$8.4 million in the comparable prior year period. In the first nine months of fiscal year 2012, we made principal payments of $11.3 million on the term loan indebtedness to pay it off entirely, had net payments on our revolving loan of
$9.9 million and cleared the book overdraft outstanding at July 31, 2011 of $2.9 million. The book overdraft represented the amount in excess of the bank cash balance necessary to fund the checks that were paid but not yet cleared. In the
prior year period, we had a net payment on our revolving loan of $2.1 million and principal payments on our term loan of $6.0 million. In the nine month periods ended April 30, 2012 and 2011, we paid dividends of $908,000 and $735,000,
respectively. It is our policy to pay dividends from available cash after taking into consideration our profitability, capital requirements, financial condition, growth, business opportunities and other factors which our board of directors may deem
relevant.

18

Working Capital

We have a revolving line of credit under an amended and restated credit agreement. At April 30, 2012, we had $8.0 million outstanding under that revolving facility.

Management believes that our current credit facility, combined with cash flows from operations, will adequately provide for our working
capital needs for current operations for the next twelve months.

Long Term Obligations

To finance the acquisition of the electronic chemicals business in December 2007, we entered into a credit agreement and a note purchase
agreement with Wachovia Bank, National Association, a subsidiary of Wells Fargo & Co., Bank of America, N.A., The Prudential Insurance Company of America, and Pruco Life Insurance Company. The credit facility included a revolving loan
facility and a term loan facility.

We amended the credit agreement in March 2010, and amended it again in November 2011. The
November 2011 amendment of the credit facility raises the maximum amount that may be borrowed under the revolving loan facility from $50.0 million to $60.0 million, extends the maturity date of the credit agreement to December 31, 2016 and
allows advances under the revolving loan facility without reference to a borrowing base restriction. The financial covenant for debt to capitalization was replaced by a current ratio minimum of 1.5 to 1.0. During the first quarter of fiscal year
2012 we paid off all outstanding advances under the credit facilitys term loan commitment, and in the November 2011 amendment, that aspect of the facility was deleted.

Advances under the revolving loan facility mature December 31, 2016 and bears interest at a varying rate of LIBOR plus a margin based on our funded debt to EBITDA, as described below.

Advances outstanding under the revolving loan facility bear interest of 2.24% as of April 30, 2012
and June 1, 2012. Before the term loan facility was paid off and removed from the credit facility, the term facility required principal payments of $458,333 per month for the first 24 months, then beginning January 2010 principal payments
became $666,667 per month for the balance of the term prior to maturity. On March 2, 2012, we repaid $10.0 million of the balance on the revolving loan facility from proceeds received from the sale of the animal health business. At
April 30, 2012, $8.0 million was outstanding on the revolving facility.

The financing for the acquisition of the
electronic chemicals business in fiscal year 2008 included a $20.0 million note purchase agreement with the Prudential Insurance Company of America. Advances under the note purchase agreement mature December 31, 2014, and bear interest at
7.43% per annum. Principal is payable at maturity. At April 30, 2012, $20.0 million was outstanding under the note purchase agreement.

Loans under the amended and restated credit facility and the note purchase agreement are secured by our assets, including inventory, accounts receivable, equipment, intangible assets and real property.
The credit facility and the note purchase agreement have restrictive covenants, including that we must maintain a fixed charge coverage ratio of 1.5 to 1.0, a ratio of funded debt to EBITDA of 3.0 to 1.0, and a current ratio of at least 1.5 to 1.0.
For purposes of calculating these financial covenant ratios, we use a pro forma EBITDA. On April 30, 2012, we were in compliance with all of our debt covenants.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements,
such as financing or unconsolidated variable interest entities.

Disclosure Regarding Forward Looking Statements

We are including the following discussion to inform our existing and potential security holders generally of some of the risks and
uncertainties that can affect us and to take advantage of the safe harbor protection for forward-looking statements that applicable federal securities law affords. From time to time, our management or persons acting on our behalf make
forward-looking statements to inform existing and potential security holders about our company. These forward-looking statements include information about possible or assumed future results of our operations. All statements, other than statements of
historical facts, included or incorporated by reference in this report that address activities, events or developments that we expect or anticipate may occur in the future, including such things as future capital expenditures, business strategy,
competitive strengths, goals, growth of our business and operations, plans and references to future successes may be considered forward-looking statements. Also, when we use words such as anticipate, believe,
estimate, intend, plan, project, forecast, may, should, budget, goal, expect, probably or similar expressions, we are
making forward-looking statements. Many risks and uncertainties may impact the matters addressed in these forward-looking statements. Our forward-looking statements speak only as of the date made and we will not update forward-looking statements
unless the securities laws require us to do so.

Some of the key factors which could cause our future financial results and
performance to vary from those expected include:

market developments affecting, and other changes in, the demand for our products and the entry of new competitors or the introduction of new competing
products;



availability or increases in the price of our primary raw materials or active ingredients;



the timing of planned capital expenditures;



our ability to identify, develop or acquire, and market additional product lines and businesses necessary to implement our business strategy and our
ability to finance such acquisitions and development;



the condition of the capital markets generally, which will be affected by interest rates, foreign currency fluctuations and general economic
conditions;



cost and other effects of legal and administrative proceedings, settlements, investigations and claims, including environmental liabilities which may
not be covered by indemnity or insurance;



the effects of weather, earthquakes, other natural disasters and terrorist attacks;



the ability to obtain registration and re-registration of our products under applicable law;



the political and economic climate in the foreign or domestic jurisdictions in which we conduct business or instability in a region due to criminal
activity; and



other United States or foreign regulatory or legislative developments which affect the demand for our products generally or increase the environmental
compliance cost for our products or impose liabilities on the manufacturers and distributors of such products.

The information contained in this report, including the information set forth under the heading Risk Factors, identifies additional factors that could cause our results or performance to
differ materially from those we express in our forward-looking statements. Although we believe that the assumptions underlying our forward-looking statements are reasonable, any of these assumptions and, therefore, the forward-looking statements
based on these assumptions, could themselves prove to be inaccurate. In light of the significant uncertainties inherent in the forward-looking statements which are included in this report and the exhibits and other documents incorporated herein by
reference, our inclusion of this information is not a representation by us or any other person that our objectives and plans will be achieved.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

We are exposed to certain market risks in the ordinary course of our business, arising primarily from changes in interest rates and to a lesser extent foreign currency exchange rate fluctuations.
Generally we do not utilize derivative financial instruments or hedging transactions to manage that risk. Our exposure to interest rate risk and foreign currency risk is discussed in our Annual Report on Form 10-K for the fiscal year ended
July 31, 2011. There has been no material change in that information.

ITEM 4.

CONTROLS AND PROCEDURES

The term disclosure controls and procedures is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of

and reported within the time periods specified by the Securities and Exchange Commission. Our management, including our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as
of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by
this report.

There were no changes to our internal control over financial reporting during the quarterly period covered by
this Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
